The present work studied the data from a 34 years old long-term rice–wheat cropping sequence to evaluate the effects of integrated nutrient management (INM) on secondary and micronutrient under alluvial soil. The treatment included three organic sources viz. FYM, wheat straw (WS) and green manuring (GM) with Sesbania aculeate replacing 25% and 50% of the optimum N during kharif season, treatment replacing 50% N through organic manure were given 100% RDF in wheat while those receiving 25% N replacement in rice got only 75% RDF in wheat. The results indicated that the replacement of 50% and 25% N of RDF to rice through organics either FYM/GM/ WS, significantly augment the DTPA-Zn, Cu, Fe &Mn, available S and boron (B) content of post-harvest soil. It has been found that the integrated nutrient management increased the soil DTPA extractable Zn from 38 - 75%, Cu 38 - 72%, Fe 27 - 53%, Mn 14 - 57%, Available S 68 - 95%, and hot water soluble B 93 - 160%, than 100% RDF over a period of 34 years continuous cultivation might be due to the prominent contribution of INM leads to maintain the soil heath and it developed inherent capacity of soil as compare to sole mineral fertilization.
